Now online @pnas.org: We developed a simple, scalable, and accessible platform for deep profiling of phosphoeraser specificity using human phosphoproteome-derived peptide libraries (PhosPropels!) 🧪👩‍🔬https://www.pnas.org/doi/10.1073/pnas.2523183123

Excited that our paper on enzymatic bromination of peptides is now online at ACS Chemical Biology! Led by Haley Bridge, we showed that the flavin-dependent halogenase RebH and its variants can be used for late-stage chemoenzymatic diversification of bioactive peptides: pubs.acs.org/doi/10.1021/...

Enzymatic Bromination of Native Peptides for Late-Stage Structural Diversification via Suzuki–Miyaura Coupling
Flavin-dependent halogenases (FDHs) provide a biocatalytic approach for the site-selective halogenation of aromatic compounds, but their use in late-stage functionalization of peptides has remained li...

Position-specific frequency matrices can be used to calculate z-scores comparing enzyme-treated and control samples. The z-scores are plotted as heatmaps that represent an enzyme specificity profile.

Excited to share our latest: we engineered the reactivity of a bacterial E1-like enzyme for ATP-driven modification of C termini. Our tool mimics the logic of peptide bond formation in biology for precision modification of proteins in vitro. 🧪https://rdcu.be/ewN7C
